Going through this now. Make sure you do your conductor plate before you do anything. That will eliminate the issue with the car going into limp mode when you hit the pedal switch. I am working with Troy. He has been great.

There is a switch under the accelerator pedal that you use to reset your TCU learn mode. I’ve heard it also acts like a kick down switch for the transmission as well. Not sure about that mine usually kicks down way before i reach half throttle. My car would go into limp mode if I pressed on the throttle and depressed that switch. After I changed the conductor plate it doesn’t do that anymore.

In my limp mode instances under full throttle, accelerator pedal was overextended, causing the ECU to see to high of a voltage reading. I am not aware of a switch in this assembly. .
Not sure how the conductor plate remedied your situation, but the pedal assembly has fixed this many times. One of 230s I have did this, and a small spacer between the plastic pedal and base cured the issue.
